'Application filed November 1917. Serial No. 200.800. i

T 0 all whom. it may concern:

ie it known that I, WALKER Boo'rrn-a citizen of the United States, residing-at till Frazer avenue, Collingswood, in the county of Camden and State of New Jersey, have invented new and useful Improvements in Stylus-Holders, of which the following is a specification.

The invention relates to soundboxes, such as used in connection with phonographs or other talking machines, and has for an object to provide a holder for the stylus of the soundbox.

The -invention comprehends among other features, the provision of a simple holder for securing the free end of the stylus arm with relation to the soundbox proper,'the invention being of a form which will enable the same to be made very cheaply, and readily applied, and also permit of securing the stylus arm to the desired degree of rigidity, so that the most effective sound results can be obtained, and whereby further adj ustment of the connection can be obtained.

In the further disclosure of the invention, reference is to be had to the accompanying drawing, constituting a part of this specification, and in which similar characters of reference denote corresponding parts in all the views, and in which Figure 1 is a side elevation of the soundbOX showing my device applied thereto.

Fig. 2 is a face view of the structure shown in Fig. 1.

Fig. 3 is a bottom plan view, and

Fig. -1 is a fragmentary bottom plan sectional view showing mechanical details.

Referring more particularly to the views, 10 indicates a soundbox having the usual diaphragm 11, to the center of which one end of the usual stylus'12 is secured, said stylus projecting parallel to the face'of the diaphragm and beyond the edgethereof, and adapted to receive the usual sound needle 13 secured by the usual screw 1st. In order to secure the free end of the stylus arm rigid with respect to the soundbox. 10, I provide a holder or support which in its entirety is indicated by the numeral 15, and which indetail embodies a T-shaped plate16 secured to the under side of the soundbox 10 by a threaded stud or projection 1", which is formed .with and extends through a tubular internally threaded sleeve 18, said stud being i-llrtmlflddkgbllgll the plate 16 and into the Specification o fLetters ifatent.

of the plate. A threaded pin 20 serves as the fulcrum or pivotal point for a pair of arms 21 in the nature of toggles. of a scissors-like construction, having their forward pointed ends 22 projecting intorecesses 23 formed in the stylus arm-12, the rear ends of said arms being provided with transverse openings 24: through which are loosely passed suitable adjusting screws 25, threaded into the sleeve 18.

From the foregoing it will be seen that the various parts described can be readily assembled, and it will be clear that when the screws 25 are screwed up into the cylinder 18, it will force the forward pointed ends 21 of the arms into positive and absolute engagement with the stylus arm by extending into the recesses 22, and as the screws are tightened up, a rigid connection between the stylus arm and the soundbox will be assured. It will be clear also that the particular holder or connection, provides for an adjustment so that the desired rigid connections between the free end of the stylus arm and. sound box can .be. varied and easily adjusted by tightening or loosening the screws 25.

It will be understood that I do not limitmyself to the particular form of construc tion shown; that various slight changes may be made without departing from the spirit of the invention. the scope of which is defined in the appended claims.

I claim.

1. A holder for the stylus of a sou'mlbox comprising a plate secured to the soundbox. pivoted arms supported on the plate and having-their forward ends for engagementwith the free end of the stylus arm, a sleeve interposed between the rear ends of said arms, and screws passing through the rear ends of the arms and engaging with the sleeve, whereby the rear ends of said .arms can be moved toward each other to insure a rigid connection between the forward ends of the arms and the stylus.

2. A holder for the stylus of a soundbox comprising a plurality of crossed pivoted arms movably supported on the soundbox, with the front ends of the arms engaging the stylus, and means for moving the rear gt-he sleeve" extend "mg at right-angles to a pro ectlng part 19 ends of said arms toward each other to insure rigid connection between the stylus and front end of said arms.

3. A holder for the stylus of a soundbox comprising a plate on the soundbox, a plurality of toggle arms pivoted on the plate, with the forward ends of said arms engaging the stylus, a sleeve, a stud on the sleeve and threaded on to the plate to support the sleeve "thereon," and screws passing through the rear ends of the arms and in threaded connection with the sleeve, whereby when said screws are tightened, with respect to the sleeve, the forward ends of the arms will be rigidly engaged with the stylus.

4. In a device of the character described, a soundbox having a stylus, a support carried by the soundbox, crossed arms pivoted to the support, and means operating on one of the ends of said arms, to clamp the op- 2L posite ends of said arms against'the stylus.

In testimony whereof I aflix my signature.
